Since 1975, flood estimation in Ireland has generally followed
methods as outlined in the Flood Studies Report (Natural Environment Research Council, 1975). An update of this for conditions in the Republic of Ireland commenced
in 2005 and included research in Urban Catchment Flood Analysis. To
inform this work, a scoping study of issues relating to flooding
caused by urban runoff was undertaken by a team from the Centre for
Water Resources Research at University College Dublin and some of
the findings are described in this paper. It focussed on
quantitative and qualitative research methods (self-completion
questionnaires and Focus Groups) to review the methods of flood
estimation for urbanised catchments currently in use in Ireland. It
assessed the nature of deficiencies associated with urban-runoff
control and identified achievable and realistic objectives for
further research. A questionnaire was developed around a number of
key themes pertaining to flooding caused by urban runoff and
circulated to 291 stakeholders in target sectors that ranged from
Engineering Consultancies to Academic Institutions. A total of 100
questionnaires were returned giving a 34% response rate. The study
found; (i) a proliferation of methods are used in practice resulting in significant differences between the estimates; (ii) some methods
are sometimes being used for inappropriate spatial scales; (iii)
there is a lack of clear guidance on the use of the methods and/or
associated software packages; (iv) there is little appreciation of
the uncertainties associated with the methods and (v) there are
significant deficiencies in some of the basic information available.
A list of recommendations was produced, to guide the commissioning
of future research to improve the methods available to designers. |
